Title: Component mounting method for double-side mount board
Inventor: YODA TOMOYA
IPC: H05K1/18
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To achieve improved component mounting on double-side mount boards both on their front side and on their rear side by plane-symmetrically setting component mount positions on boards, and alternately arranging the front sides and rear sides of these boards. SOLUTION: When a work board 20 is transferred, a chip mounter mounts electronic components 11A in the electronic component mount positions 12A on boards 10 with their front sides A facing this side of the figure. The chip mounter also mounts electronic components 11B in the electronic component mount positions 2B on boards 10 with their rear sides B facing this side of the figure. Then the work boar 20 with the components mounted is subjected to reflow, and is turned over by a lifter. The electronic component mount positions 12A, 12B on the boards 10 set on the work board 20 turned over are exactly in the same state as were before the work board is turned over. Therefore, the mounting jigs and mounting program used before the work board is turned over can be used for the group of the boards turned over. This reduces cost for creating the mounting jigs and program and work cost.

Abstract: PURPOSE: To prevent the breakage of a film by the rotation of a soln. in a vessel at the time of placing a substrate in the soln. in the vessel to form a film on the substrate by natural settling and rotating the vessel with a centrifugal separator to exert a centrifugal force on the film and increasing the density of the film. CONSTITUTION: The inside of a cylindrical vessel 10 is divided into plural spaces by the plural flat partition walls 11 radiated from the center axis C of the vessel. A substrate 12 on which a phosphor film is to be formed is placed on the bottom face 10a in the vessel 10, and a phosphor film forming soln. prepared by dispersing the particles of a phosphor is put in the vessel 10. The phosphor particles in the soln. are naturally settled on the substrate 12, and the phosphor film is formed on the substrate 12. A centrifugal separator is driven to revolve the vessel 10 with a rotating shaft outside the vessel 10 as a center. As the center axis C in the vessel 10 is inclined toward horizontal from vertical, a difference in centrifugal force is caused in the soln. due to the difference in the radius of gyration.  Since the soln. is rotated in each space divided by the partition wall, the phosphor film is not disturbed.
